Google DeepMind’s AlphaGo computer program took an insurmountable 3-1 lead over Go champion Lee Se-dol Saturday in a five-game series.
The Chinese board game is considered to be more complex for computers than games like chess, because of the greater amount of possible outcomes.
“To be honest, we are a bit stunned and speechless,” DeepMind CEO Demis Hassabis said.
The program’s third consecutive win happened in five hours Saturday while Se-dol rallied to win the competition’s fourth game on Sunday.
“I kind of felt powerless,” Se-dol said. “I have extensive experience in playing Go but there was never a case where I was under this much pressure and I was incapable of overcoming it.”
